An aircraft moves at a speed of 180 meters per second for nine seconds. How far does the aircraft move?

Here, we are asked to find how far the aircraft travels when given the speed of the aircraft and the time for which the aircraft travels. Recall that speed is the distance an object travels divided by the time that the object travels for.

Because we are asked to find the distance traveled, let’s start by getting the distance by itself on one side of the equation. We can do this by multiplying both sides of the equation for speed by the time of nine seconds. When we do this, we see that on the left-hand side of the equation, we find that 180 meters per second multiplied by nine seconds is equal to the distance traveled. Multiplying 180 by nine, we get 1620.

But before we choose our answer, let’s take a look at the units we have. On the left-hand side of the equation, we have the unit of meters over seconds multiplied by seconds. The unit of seconds in the time cancels the unit of seconds in the speed. We are left with units of meters on the left-hand side of the equation. This matches the units of distance. So, the distance traveled by the aircraft is 1620 meters.
